How to set up Keyshade in a Python app.

Keyshade is a secure, runtime alternative to .env files — it keeps your secrets and environment variables safe, without ever needing to commit them to your repo.

This guide walks you through integrating Keyshade into your Python app, step by step — no import os gymnastics required.

Coming Up

Here's what this guide covers:

• Create a Python app

• Install the Keyshade CLI

• Set up a profile using your API key

• Create a project and environment in the Keyshade dashboard

• Add secrets and runtime variables

• Link your local project with keyshade init

• Run your app with keyshade run

• Use os.environ to access values in your Python code

💡 First time using Keyshade? We recommend starting with What is Keyshade? to get familiar with how it works.

Create a Python Project

If you don't already have a Python app, create one with a virtual environment:

mkdir <your-app-name>
cd <your-app-name>
python -m venv venv
source venv/bin/activate # On Windows: venv\Scripts\activate

See the official Python documentation on venv for more details.

Install the Keyshade CLI

The Keyshade CLI lets you fetch secrets, inject env variables, and manage profiles all from your terminal.

Install it globally:

npm install -g @keyshade/cli

Note: Node.js v24 may cause issues with the Keyshade CLI, so use v20 (LTS) for best compatibility.

See Installing the CLI for more info.

Set Up Your Profile

To connect your local environment with Keyshade, create or use a profile.

If this is your first time using Keyshade, follow this guide to set up your profile.

If you've already used Keyshade before:

keyshade profile use <your-profile-name>

You can verify which profile is active with:

keyshade workspace list

Create a Project and Add Secrets

To get started:

1. Go to the Keyshade Dashboard

2. Click "Create Project"

3. Name your project (e.g. python-app)

4. Inside the project, click the "Secrets" tab

5. Add your secrets (e.g. API_KEY, DATABASE_URL)

6. Add your variables (e.g. PORT)

💡 Secrets vs Variables:

• Secrets are sensitive credentials, such as API keys or access tokens. These are securely encrypted by Keyshade to keep them protected.

• Variables are non-sensitive configuration values, like port numbers, feature flags, or environment modes. These are stored in plain text and are not encrypted.

Initialize Keyshade in Your Project

In order to use the configurations you just created on the dashboard, you would need to initialize keyshade in your project. This generates the necessary configurations for the CLI to tap into your keyshade project.

From your project root:

cd <your-app-name>

Run the init command to link your local project with the Keyshade dashboard:

keyshade init

You'll be guided through selecting your workspace, project, and environment.

Want to skip the prompts?

keyshade init --workspace-slug <my-workspace> --project-slug <my-project> --environment-slug <my-environment> --private-key <my-private-key>

This will generate a keyshade.json file in your project root.

Run Your App with Secure Env Injection

Start your Python app with Keyshade:

For a simple Python script:

keyshade run -- python main.py

For web frameworks:

keyshade run -- flask run
keyshade run -- uvicorn app:app --reload
keyshade run -- python manage.py runserver

Example Output:

Python Run

Keyshade will inject your secrets and variables securely at runtime.

Access Secrets and Variables in Your Code

Once your app is running with keyshade run, use os.environ to access any injected values — no extra setup needed.

For example, if you added secrets named DATABASE_URL and API_KEY, and a variable named PORT in the Keyshade dashboard:

db_url = os.environ.get("DATABASE_URL")
port = int(os.environ.get("PORT", 5000))
api_key = os.environ.get("API_KEY")

Example Flask Application

Create a simple Flask app in app.py:

Flask app

Now use keyshade run -- python app.py to start your Flask server with all secrets securely injected.

Visit http://localhost:5000 to confirm your secrets are being loaded properly.

You're All Set 🎊

Your Python app is now securely powered by Keyshade — no .env files, no leaking secrets, and no environment mismatches.
